Kind Relief

Jason was confused as to why his dick did not at all react to any of his attempts to get it back down anymore, and too horny to think straight thanks to his almost painfully erect cock. Just one look at his mother's giant tits caused blood to rush into his organ and it to be throbbing at it's very limits. He had been trying to do math in his head, thought of the most annoying school moments, yet his dick did not care and just stood there ready to go. And at this new size her mother accidentally made him, it was clouding his mind putting him into a horny haze, till all he could still focus on were those massive, delicious tits dangling right in front of him, ready to be used.
"I ... need to cum." he mumbled, eyes rolling around, as he desperately tried to focus yet failed.
"Good boy..." Beth soothed him, and wrapped her massive rack around his shaft.

It took exactly one pump to make Jason groan aloud and get to the edge, the almost tormenting level of erection did the rest. Three more pumps and Jason's head tilted back. A second later his oversized pillar of cock started to shoot almost humiliating tiny amount of juice. Nevertheless Beth did her best to milk that dick dry with her rack, till Jason eventually collapsed into his chair. It took him a moment to come back to this world, where his ejected fluids were now running down his mother's tits right in front of him.
"Why is my dick still this hard after that?" he mumbled with an exhausted voice, and then realized with a now much clearer mind that he was sitting right in front of his mom with his massive boner on full display. "C-can we now turn this back down?" But Beth just smiled.
"I think you should keep it, it suits you." she teased him "But I think there is one thing we need to fix..." she turned around and started to type into the box again. Jason was too exhausted to stop her, but also couldn't see much of what she was writing, as her huge tits blocked his view. Suddenly a tingle in his balls though told him what she had been adjusting, and he watched them expand till they were the size of tennis balls. And they felt full... very full!

"Why are you doing this?!" he asked confused right into the motherly smile on Beth' face.
"You really need to get laid, son!" she threw the hard truth into his face with a chuckle. "And this will help."
"D-do girls like big dicks?" Jason wondered, his mother immediately nodded.
"They totally do!" she lied. Some did, sure, but the actual plan in her mind was that now they'd be looking at him and the first thing they'd have on their mind is his dick, and with that associate him with cock and sex. "It will totally get you laid." she added with a warm smile. Jason looked uneasy, but in the end trusted her. "Now if you don't mind, I'd like to try a few things with this machine. In private." Beth continued and left his lap. Jason stared at the gigantic boner dangling in front of him, smelled the stench of his just launched sperm drying in the air, and wasn't sure what to make of this.
"I... just stay like this then?" he wondered. Beth nodded.
"Believe me, it will be amazing!" she cheered at him. Jason was not yet convinced, but being the good, agreeable boy he was, he didn't question her judgement any further.
"Ok..." he simply said and tried to pull his pants back together, but that cock did not care to hide beneath his clothes again. In the end he left with it jiggling left to right, and his now much bigger balls hitting his thighs below.

Back in his room Jason stared at his now semi-erect dick. It still was almost the size of his arm, and aside from fully flaccid he probably would have a tough time hiding that thing. While it had been going into that direction since he left his mother's room, the second he thought back to what had just happened, it turned upwards again. A constant up and down, depending on where his thoughts drifted to. Nothing he tried could prevent that from happening, and he had to just accept that somehow his cock would now immediately get erect whenever he was experiencing even the slightest bit of arousal.
"Fuck..." he cursed as he begun to understand what kind of an issue that would be. It's not that he didn't like his new size, in fact he had been dreaming about being this big at times, but then living out a wet dream in the real world was a completely different challenge. But he trusted his mom, she probably knew what was good for him. And maybe that powerful program would somehow make the world ok with this. Then suddenly a loud moan came from Beth's room, making it very clear that she was having one hell of an orgasm at this very moment. When Jason's thoughts returned he stared at his throbbing, full-mast erection again. "Fuck!!" he cursed. If any girl at school would flash her tits at him, he'd be like this in an instant. Not that anyone would, but the thought was nice. And got his dick even harder. There was probably only one way left to get this thing back down.

Pumping a cock that reached up to his face with both hands and still having enough room for maybe two more hands was as exciting as it was scary. The head of this monster dangled in front of him, and after some hesitation he gave into the urge to try. The salty taste on his tongue was irritating, but once he got himself to wrap his lips around the tip just as his mother did, he was rewarded with an amazing feeling. He just had to give it a try, and as he was doing it it dawned on him how much pleasure he was now capable of giving himself. Briefly Jason wondered if this was also part of his mother's plan, but soon enough the strong arousal radiating from this huge organ took over his mind again, and his lips sucking hard on the tip. He used to have his mind under control, but now with a five times bigger cock, it also had become five times more intense, and with that five times more difficult to not get lost in arousal. And he definitely did get lost thinking about what had happened earlier. That and a bit of sucking and pumping got him over the edge again within just a few minutes. Yet right from the moment the orgasm started building he knew something was different. But this was too needed and way too late to be stopped. He unplugged his cock from his mouth and let go. But what erupted from it was beyond his wildest dreams. Under his loud moans a jet of white liquid shot out, easily the entire volume of his complete orgasm from before, probably more. It shot high into the air and splattered on the ground, with a new jet of equal volume following in between.
"Wh-a-..." he stammered, but the orgasm took over. Load after load he blasted into his room, causing a big mess. Panting and groaning he tried his best to not get too much onto himself, but when it was finally over he realized that not only he had to shower now, he also had to mop a literal puddle of his own cum the floor. His juice was running down all his body, and it looked like someone splashed a full glass of it onto him.
"What the hell did she do to me?!" he mumbled, but the movement and gurgling from his balls already gave him the answer. Apparently his mom not only wanted him to be huge, but also very productive. And his massive schlong just stood there still throbbing, like he hadn't just cum out his soul a few seconds earlier...
